To all whom it may concern: I

Be it known that I, WILLiAM J. ONEIL, a

States, residing at Akro'n, in the county of Summit and State of Ohio,have invented new and useful Improvements in Protectors and Reinforce- Mof which the following is a specification. This invention relates to aprotector and reinforcement for pneumatic tires, designed beused withinthe case or sheath of the tire to reinforce the same and to cover the toprotect the latter from puncturing. The invention has'for one of itsobjects to provide a device of this character so designed as to be usedas an attachment for tires of ble and of protector being constructed ofen erimposed avers of duck or similar materia shaped on a suitable formand bound tocether by vulcanizing the rubber cutting tie surfacesof thelayers.

Another object of the invention is the provision of a simple andeflective means for securing the protector and reinforcement in place byattaching the same to the valve stem. of the inner tube so that grippingor lateral displacement is effectively prevented.

, will appear as the With these objects 1n view and others, asdescription proceeds, the lnventlon comprises the various novel featuresof construction and arrangement of arts which will be more fullydescribed ereinafter and set forth with particularity m the claimappended hereto.

' cent the securing rubb t e accom anying drawing, which illustrates oneemilbdiment of the invention, Figure 1 is a perspective view of the tireprotector and relnforcement. Fi 2 is a transverse "section thereof takenon line 22, Fig. showin the relation of the same to the parts of t etire. Fig. 3 is a fragmentary plan view of the ortion of the deviceadja- -'tional view on line 4-4, F1 3. Fig. 5 is a sectional view of aportion 0 one of the duck layers of the device showing the oppositefaces thereof covered with unvulcanized Similar reference characters areemployed to designate corresponding parts throughout the several views.

be and makeswithout changing. the inner tube, and which is light andflexi-' such shape as to conform to the 0 case and inner tube, thereinforcement and;

and. 4 is detail sec-- Referring to the drawing, A designates theprotector and reinforcement of the tire which is of annular form to fitin the case of the tire and is of crescentshaped cross section to beaccommodated between the case and inner tube of a tire, the device beingof such length as to overlap at the ends 1 to form a com lete protectoraround the tire. At a suit-ab e point, the device is provided with aband B securedin place in any suit able manner and of such len th as toextend. entirely around the inner tu e and overlap, and the overlappingportions or ears 2 are provided'with apertures 3 for receiving the valvestem of the inner tube so that'creeping of the device or transversedisplacement will revented. y reference to Fig. 2, it will be observedthat the device A fits into the case or sheath that extends approximatelaround the outer half thereof to protect t at portion of the tireexposed to puncturable objects, and fitting in the case and under thereinforcing and protecting device A is the inner tube D of the pneumatictire. The tube D is provided with the usual valve stem 4 that extendsthrough the fell of the wheel to which the tire is applie and this stempasses through the apertures 3 of the ears formed by the extremity ofthe transversely-extending band B, these cars being disposed between theinner tube and the base of the casing, as shown.

he protecting and reinforcing device A is composed of a plurality of suerimposed layers 6, 7, 8 and 9, of duck or otl ier sultable materialcapable of resisting the penetration of nails, glass or the like. Anydesired number of layers may be employed but in the present instanceonly four are shown, and the layer 6 is of greater width than theincanized rubber designated by 10, Fig.5, for a appear, and thesepurpose hereinafter to and bottom covers ayers are covered by top tireand on 11 and 12 of suitable flexible fabric. The fastening and 14 offabric similar'to the coverings L1 and 12, one of which extends overtheoutside layer and under the outer covering 11, while the other stripextends between the inner layer of duck and the bottom covering, theends of the strips being stuck together by vulcanizing rubber betweenthem or in any other suitable manner so as to obtain the re uiredstrength.

n constructing the protecting and reinforcing device, a circular form ofsuitable diameter is required that has an outer surface of convex crosssection to-correspond to the transverse contour of the inner tube of thethis form is placed the strip of fabric constitutin the under covering12. At a suitable poin onthis covering is positioned the strip 13 of thesecuring band B, and over these two pieces is (placed the first layer 6.This layer is rolle down to conform to the shape of the form and thenthe other layers are successively placed in position and separatelyrolled to the form, the longitudinal center lines of the respectivelayers being coincident with each other. After the layers of duck arethus applied, the second strip 14 of the securing band is ositioned onthe partly formed device an the outer covering 11 then applied, theinner and outer coverings being arranged with their corres onding edgesmeeting. The article, whic 1 is now completely formed, is wrapped withcloth and put in a heater for vulcanization, the rubber coating thelayers serving as bindings not only between the layers but between thefabric coverings '11 and 12 and strips 13 and 14 of the securing band,so that no fastenings are required band B comprises two strips 13 parentto those s invention appertains, scribed the principle emcee since thearticle becomes of substantially unitary or integral structure.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction an the methodof 0' eration will be readil alpliilled in the art to whic t e and whileI have deof o eration of the invention, together with t e device which.now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and thatsuch'changes may be made when desired as are within the scope of theclaim ap ended heretoj aving thus described the invention, what I claimisz- A protecting and reinforcing device coustituting an attachment forinner tube pneumatic tires and adapted to be inserted within the sheathof the tire and around the inner tube thereof, said device consisting ofa flexible member of greater length than the circumference of the innertube to extend entirely around the same with its ends overlapping, andan attaching band fixedly secured to the member and extendingtransversely thereto, said band being of such length as to embrace theinner tube in a transverse plane and to have its ends overlapping, sardoverlapping ends of the band being apertured to receive the stem of theinner tube.

In testimony whereof I aflix my'signature in presence of two witnesses.
